Ashrae Duct Fitting Database Excel ★ Premium & Verified

Essentially, it is the lookup table on steroids, ready for formula-driven analysis.

Engineers often use the software to calculate individual pressure drops for each fitting (in Pascals or inches w.g.) and then manually transfer these values into an Excel-based ESP Calculation Sheet to sum the total system losses. ashrae duct fitting database excel

Easily sum losses along the "longest route" or the path with the highest resistance. Essentially, it is the lookup table on steroids,

The ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) Duct Fitting Database is a collection of pressure loss data for various duct fittings, such as elbows, tees, and transitions. The database provides a comprehensive source of information for calculating pressure losses in duct systems. The ASHRAE (American Society of Heating, Refrigerating, and

: Identify the longest duct run or the route with the most complex fittings (the path of highest resistance). Input Fitting Data : For each section, use the ASHRAE DFDB software to get the pressure loss (in Pascals or inches w.g.). Sum the Losses : Your Excel sheet should total the losses from: Straight Ducts : Calculated as (Length × Friction Rate).

The ASHRAE Duct Fitting Database (DFDB) is a comprehensive digital library used by HVAC engineers to calculate pressure losses across more than 200 types of round, rectangular, and flat oval fittings. While the core database is provided as a or a mobile app, many professionals integrate this data into Excel spreadsheets to perform the total External Static Pressure (ESP) calculations required for sizing fans and air handling equipment.
